Did you ever hear the expression, “Give them an inch and they’ll take a mile”? It basically means that if you make a small concession for someone, that person will be emboldened to take further advantage of you, instead of being content with what you have given them.
This is the trap the Republicans have fallen into. They have kowtowed to Trump and freely given him just about every “inch” he’s demanded.
So, that old saying about giving an inch and taking a mile needs to be updated in the era of Donald Trump.
